The ccpc provincial competition hand-speed copper, let’s talk about the test situation at that time. I
made one at hand speed in the first seven minutes, and did not make one in the next 5 hours.
First, I did the string inversion. I did a similar question on cf before. I thought it was quite simple. The example was passed, the chestnut I found myself was passed, but I don’t know where I got stuck,
and then the interstellar celestial whirlwind. I thought it was a simple small project to build bugs, protoss, Attack incident. The example is also passed, but it’s not right. After the end, the group sent out ideas, and then studied and researched and
finally it was the sun bombing. This was done by my teammate. He came up with a formula according to the question and asked for it, but it has not been right. . I heard the seniors mean that it was designed with high precision, so it’s not right.
In short, this competition was very difficult, and I found my own shortcomings. Many provincial competitions involve mathematical knowledge, but the current level is not enough.
